This paper builds a general mathematical and algorithmic theory for
balloon-twisting structures, from balloon animals to balloon polyhedra, by
modeling their underlying graphs (edge skeleta). In particular, we give
algorithms to find the fewest balloons that can make exactly a desired graph
or, using fewer balloons but allowing repeated traversal or shortcuts, the
minimum total length needed by a given number of balloons. In contrast, we
show NP-completeness of determining whether such an optimal construction is
possible with balloons of equal length.
